  1. Search And Rescue Satellite Aided Tracking System How much is your life worth? Consider getting a 406 MHz ELT for your aircraft

  2. Beacon Segment until 2009 • Two types: 121.5/243 MHz and 406 MHz • Three applications: • Emergency Position Indication Radio Beacons (EPIRB) for Maritime Uses • Emergency Locator Transmitters (ELT) for Aviation Uses • - Personal Locator Beacons (PLB) for Remote Area Recreational users, aviators.

  3. 121.5 MHz Termination Date • 1 Feb 2009 – Receivers on space craft will be shut off • 121.5 MHz ELTs will no longer be picked up by the satellite systems

  4. 121.5 MHz Beacons • Older technology • Not designed for satellite processing (no store & forward capability) • Analog signal only = no identification code • Does not have global coverage! • Low power ( < 1 watt) • Less rigid standards • Poor location accuracy = Usually no better than 12 miles = 450 SQUARE MILE SEARCH AREA • USMCC handles 250-400 ‘hits’ per day. 99.9% are false!! • - Only 1 in 8 alerts come from beacons. The rest are ATM machines, pizza ovens, and even stadium scoreboards! • - High false alert rate makes first-alert launch unfeasible…

  5. 406 MHz Beacons • New technology • Designed for satellite processing • Digital signal w/ unique identification code • Improved location accuracy • Global coverage! • Increased power ( 5 watt) • Integral 121.5 MHz homing signal (low power) • 5+ year lithium battery • Mandatory registration (no cost) • With registration information, improved location accuracy, and quicker detection times, beacon alerts can be responded to faster by search and rescue units

  6. 406MHz Location AccuracySearch Area Reduced By A Factor Of 45 Times 406.025 MHz Beacon Location Accuracy = 2.0 nm Search Area = 12.5 nm2 406 MHz Beacon w/ GPS Location Accuracy = 0.21 nm Search Area = 0.15 nm2 121.5 MHz Beacon Location Accuracy = 12nm Search Area = 452nm2

  7. Emergency Locator Transmitter ELTs are designed specifically for use aboard aircraft All ELTs have automatic (G-force/Crush force) and manual activation modes Automatically notify Federal rescue forces Mandated carriage on most General Aviation and Business Jets.

  8. Personal Locator Beacons • Not a substitute for an ELT but authorized as additional equipment • Designed for outdoor Enthusiasts • Aviators, hikers, hunters, climbers, boaters, … • Manual activation only • Automatically notify Federal rescue forces

  9. Update on US carriage requirements • DOI, NTSB, USAF, NOAA, USCG have all asked FAA to disallow 121.5 MHz ELTS as satisfying carriage requirement • FCC introducing rulemaking to disallow any new 121.5 beacons • FAA conducting Cost Benefit analysis associated with retrofit in GA aircraft • Results due out end of July 2008

  10. Update on International carriage requirements • Canada • Mandated carriage of a 406 ELT or equivalent on all Canadian Aircraft and all aircraft coming into or transiting Canada by 1 Feb 2009 currently in approval process • Mexico • Mandated carriage of 406 ELTs by 1 July 2008. • Allowance for 121.5 MHz until 1 July 2009 or until the current battery needs to be replaced, which ever happens 1st

  11. How will we find you after 1 Feb 2009 If you stay with an older 121.5 beacon?

  12. Airborne reports – if anyone is listening? FL 39000 ELT Report to AFRCC 1. First Heard 2. Strongest 3. Last Heard 4. Altitude 600 Mile Diameter ARTCC Collects ELT reports & forwards reports to the AFRCC

  13. Airborne reports – if anyone is listening? FL 39000 FL 10000 X 600 Mile Diameter 150 Mile Diameter

  14. Ground report - 121.5 MHz monitoring gaps

  15. Time is always a factor

  16. IFR Flight Plan • No communications • 30 minutes after ETA to a compulsory reporting point.

  17. VFR Flight Plan • No communications • 30 minutes after ETA to destination.

  18. NO Flight Plan(80% of General Aviation) • Reliable source reports aircraft is 1 hour overdue at destination.

  19. Timeline Review Location MISSION Active Search ? ALNOT ExCom INREQ PreCom Flight plan expires < 2 Hours 1 Hour Distress? 30-60 Min ? Page 3-B-6

  20. Survival Statistics (from AFRCC records) 100 Crash Victims 35 SURVIVE THE CRASH 21 Injured - 4 Survivors after 24 hours 14 Uninjured - 7 Survivors after 3 days - Chances for survival RAPIDLY diminish after 3 DAYS!
